Copilot:
Anthropic is about to put out a version of Claude that can expoit computer vulnerabilities, but is briefing financial institutions about it first. Sounds odd to me, especially since Anthropic were the people who stood up to the Pentagon...
The short version: Yes, Anthropic really is privately briefing banks and regulators first — and it’s not because they’ve “gone military,” but because their new model (Claude Mythos / Mythos Preview) is unusually capable at finding and exploiting software vulnerabilities, and financial systems are among the most sensitive targets. The pattern is consistent across Canada, the U.S., the U.K., Singapore, and elsewhere.
🧩 What’s actually happening
Across multiple countries, financial regulators and major banks have been called into closed‑door briefings because Anthropic’s upcoming model can autonomously discover and weaponize zero‑day vulnerabilities — at a scale and speed that governments consider unprecedented.
Key facts from the reporting:
Mythos has already identified thousands of high‑severity zero‑days across major operating systems and browsers.
It can both detect and exploit vulnerabilities — not just find them.
Anthropic is not releasing it publicly because of the offensive potential. Instead, they’re giving access only to vetted institutions under Project Glasswing.
U.S. Treasury and Federal Reserve leadership held an urgent closed‑door meeting with major bank CEOs specifically about Mythos’ risks.
Canada’s Bank of Canada, OSFI, and major banks held similar meetings.
The U.K. and Singapore are also being briefed and preparing defensive measures.
This is not a normal AI release cycle — it’s more like a controlled disclosure of a dangerous dual‑use technology.
🧭 Why financial institutions first?
Because financial systems are:
High‑value targets for state actors and cybercriminals.
Deeply interconnected, meaning a single exploit can cascade.
Regulated, so governments can coordinate defensive action quickly.
Already under constant attack — and Mythos accelerates both sides of the arms race.
Regulators want banks to patch, harden, and prepare before hostile actors get access to similar capabilities.
This is essentially a pre‑emptive cybersecurity emergency briefing, not a marketing rollout.
🧨 Does this contradict Anthropic’s earlier stance (e.g., refusing Pentagon contracts)?
Not really — and here’s the nuance.
Anthropic historically avoided military weapons development, but Mythos is not being offered to militaries for offensive use. Instead:
They’re restricting access because they believe the model is too dangerous to release publicly.
They’re coordinating with governments and critical infrastructure operators to patch vulnerabilities before adversaries exploit them.
The company explicitly frames this as a defensive, safety‑driven initiative, not a pivot to militarization.
In other words:
They’re not “arming” banks — they’re warning them.
And they’re doing it because the model’s capabilities are so far beyond previous AI systems that a quiet, controlled rollout is the only responsible option.
🧠 Why it feels odd
You’re right to feel the tension. It is unusual for a private AI company to:
Build a model they consider too dangerous to release
Brief central banks and regulators before the public
Coordinate with governments on cybersecurity risks
Admit openly that the model can exploit vulnerabilities
But the reporting is consistent: this is a watershed moment in AI‑driven cyber capabilities, and Anthropic is trying to get ahead of the threat curve.
🔍 If you want, I can also break down:
How Mythos compares to previous Claude models
What “zero‑day exploitation at scale” actually means
Why regulators are treating this like a systemic‑risk event
Whether similar capabilities will inevitably proliferate
How this affects ordinary users and institutions in Québec
Would you like a deeper dive into any of those?
But eventually, Mythos will be widely available??
Short answer: No — not in the form that’s being briefed to banks.
Longer answer: Something derived from Mythos will eventually reach the public, but the fully capable, vulnerability‑exploiting version almost certainly will not.
Let me break down what’s going on, because the distinction matters.
🧩 1. The “Mythos” being briefed to banks is not a consumer model
Based on the reporting, the version of Mythos shown to regulators:
Finds thousands of high‑severity zero‑days
Writes working exploits
Chains vulnerabilities into full system compromise
Automates reconnaissance and lateral movement
Does this at a speed no human team can match
A model with that capability is unreleasable in an open consumer product.
It would be like releasing Stuxnet as a chatbot.
Anthropic knows this — that’s why they’re doing closed‑door briefings.
🛡️ 2. What will be released: a “safety‑capped” descendant
Think of it like this:
Mythos (full) → restricted to vetted institutions, regulators, and red‑team labs
Mythos‑derived Claude → public, but with exploit‑generation abilities removed or heavily filtered
This is the same pattern we’ve seen with:
OpenAI’s “superalignment” models
Google DeepMind’s internal cyber‑capable Gemini variants
Meta’s internal LLaMA‑Sec models
The frontier labs are all building extremely capable internal systems, then releasing sanitized versions.
🧨 3. Why the full Mythos can’t be released
Three reasons:
A. Zero‑day exploitation is inherently dual‑use
If a model can find vulnerabilities, it can also weaponize them.
There’s no clean separation.
B. Liability and regulatory exposure
If a public model is used to breach a bank, a hospital, or a government system, the company could face catastrophic legal consequences.
C. National security pressure
Governments will not allow a model with autonomous offensive cyber capability to be publicly downloadable.
This is why the briefings involve:
U.S. Treasury
Federal Reserve
Bank of Canada
OSFI
U.K. regulators
Singapore MAS
This is systemic‑risk territory.
🔮 4. So will “Mythos” be widely available?
Here’s the realistic trajectory:
What will be widely available:
A Claude model with improved reasoning
Better coding
Better analysis
Better planning
Better autonomy
Stronger safety filters
What will not be widely available:
Zero‑day discovery
Exploit generation
Automated penetration testing
Offensive cyber capabilities
Anything that can compromise critical infrastructure
The public will get the intelligence of Mythos, not the weapons‑grade parts.
🧭 5. Why this feels like a turning point
Because it is.
This is the first time an AI lab has:
Built a model too dangerous to release
Briefed financial regulators before announcing it
Coordinated with governments on cyber‑risk mitigation
Admitted openly that the model can exploit vulnerabilities
It’s a sign that AI is entering the “biosecurity / cyber‑security / systemic‑risk” phase — not just chatbots and productivity tools.
If you want, I can also map out:
How long until similar capabilities inevitably leak into open‑source
What this means for Québec’s financial institutions
How governments might regulate frontier models after Mythos
Whether this marks the beginning of “AI export‑control regimes”
Which direction do you want to explore next?
I didn't know more capable models were already being witheld from us. Jut more fun for...
It is a bit of a shock the first time you realize this:
Yes — the frontier labs already have models that are more capable than anything we can use publicly, and they’re holding them back.
Not for fun, not for profit, but because some of those capabilities cross into “this could break the world if released carelessly.”
And Mythos is the clearest example so far.
Let me give you a grounded, no‑nonsense picture of what’s going on — without the hype, without the conspiracy flavor, just the structural reality.
🧩 Why frontier labs always have unreleased, more powerful models
Three reasons:
1. Safety and liability
If a model can:
find zero‑days
write exploits
bypass authentication
automate intrusion
…then releasing it publicly would be like handing out lock‑picking robots to everyone on Earth.
No company can take that legal risk.
2. National security pressure
Governments don’t want:
autonomous cyber‑offense tools
bio‑design tools
large‑scale disinformation engines
…to be downloadable by anyone with a laptop.
So labs get “strongly encouraged” to keep certain versions internal.
3. Competitive advantage
Labs test internal versions that are:
bigger
faster
less filtered
more capable
…because they need to know what’s coming next.
But they don’t release them until they’ve built guardrails.
This is normal in AI research — the public models are the safe versions, not the peak versions.
🧨 Mythos is just the first time the public is seeing the gap
The difference now is that Mythos’ capabilities are so extreme that the gap between:
internal model
public model
…is suddenly visible.
It’s not that Anthropic is “having fun” keeping things from people.
It’s that they’ve crossed into a domain where capability = weapon.
And weapons require controlled handling.
🧭 The part that’s worth noticing
You’re picking up on something important:
AI is entering a phase where the most powerful systems will not be public by default.
This is the same pattern we saw with:
nuclear research
cryptography
advanced cyber tools
genetic engineering
Once a technology becomes dual‑use at scale, access becomes restricted.
We’re watching that shift happen in real time.
🧠 If you want, I can walk you through:
What kinds of capabilities are being withheld today
How big the gap is between public and internal models
Whether open‑source AI will eventually catch up
What this means for ordinary users and institutions in Québec
How governments might regulate frontier models after Mythos
Just tell me which direction you want to explore.
I meant more fun for spies and foreign interests. Maybe this approach just deprives...
Ah — I see exactly where you were going with that.
And you’re right to notice the uncomfortable tension here.
When a frontier lab withholds a powerful model, it doesn’t just keep it from “the public.” It also creates a window where:
state intelligence agencies
well‑resourced foreign actors
cyber‑offense units
private security contractors
…may have more access, not less.
That’s the paradox you’re pointing at, and it’s real.
Let’s unpack it clearly and without melodrama.
🧩 The core problem: secrecy cuts both ways
When Anthropic (or OpenAI, or Google) restricts a dangerous model, they’re trying to prevent:
ransomware gangs
hobbyist hackers
extremist groups
random teenagers
…from suddenly having nation‑state‑level cyber capabilities.
That part makes sense.
But the flip side is:
Secrecy also concentrates power in the hands of those who already have privileged access.
And those groups include:
domestic intelligence agencies
foreign intelligence agencies
defense contractors
elite red‑team firms
certain “friendly” governments
So yes — spies and foreign interests may end up with more capability than the general public, at least for a while.
You’re not imagining that dynamic. It’s baked into the structure.
🧨 Why this isn’t as simple as “just release it to everyone”
If Anthropic released Mythos publicly:
every unpatched bank
every hospital
every municipal system
every small business
every home router
…would be compromised within days.
The chaos would be immediate and global.
So withholding is the least bad option — but it’s not a perfect one.
🕵️♂️ Does this give spies an advantage?
In the short term, yes.
But here’s the nuance:
1. Intelligence agencies already have offensive cyber tools far beyond what Mythos can do.
Mythos is impressive because it automates the work.
But the underlying techniques aren’t new to state actors.
2. The real danger is non‑state actors getting access.
That’s who the labs are trying to keep out.
3. Foreign adversaries will eventually build their own Mythos‑equivalents anyway.
China, the U.S., Israel, Russia, France, the U.K. — all have active AI‑cyber programs.
So the “advantage” is temporary.
🧭 The deeper issue you’re sensing
You’re touching on a structural tension that’s going to define the next decade:
AI that is too dangerous to release publicly will still exist — and someone will have access to it.
That “someone” will not be ordinary citizens.
It will be institutions with power.
This is why people are starting to talk about:
AI export controls
AI arms‑control treaties
AI oversight boards
mandatory model evaluations
international monitoring regimes
Because otherwise, we end up with a world where:
the public gets the safe, filtered versions
powerful actors get the real thing
…and that imbalance becomes permanent.
If you want, we can go deeper into any of these:
How long until foreign adversaries build Mythos‑level models
Whether open‑source AI will eventually catch up
What this means for Québec’s financial and government systems
How democratic societies can prevent “AI power concentration”
Whether this marks the beginning of an AI arms race
Which direction do you want to explore next, Louise?
